Question

I got a tricky one

When f(x) is divided by x+3, the remainder is 11 which statement must be true?

A: f(3)=-11
B:f(3)= 11
C: f(-3)= -11
D: f(-3)= 11

Good luck

Answer 1

D

Explanation:

By the remainder theorem if f(x) is divided by (x + h), then the remainder is

f(- h)

Thus f(x) divided by (x + 3) has a remainder of 11, then

f(- 3) = 11 → D
